Review on 🔌 MakerSpot Accessories - UL-Listed 5V2.4A Switching Power Supply, 22AWG 1.5M MicroUSB Cable with On/Off Switch - Raspberry Pi 3 Model B B+ Adapter/Charger by Charlie Powell

This is a USB cable with an integrated physical switch and AC/DC adapter. I use these items solely to power my Pi based projects. A physical switch in the USB cable ensures that the Pi and its associated peripherals do not receive power after the project is stopped. Power delivery from the Pi 1 Model B to the Pi 3 Model B+ is clean, stable, and reliable, with no unexpected shutdowns, power surges, or insufficient power notifications. The design of the device has evolved into a smaller, more compact form factor without a change in build quality. I can recommend it!
